I’m in need of a thread adapter with male M18x1.5 to female 1/2x28. If you can make one or point me out to one I’d really appreciate it!

Just to be clear, my suppressor has the female M18x1.5 threads to mate directly to AI barrels that used to be threaded metric years back. I’m trying to use my metric threaded can on 1/2x28 AR15 barrels. I have 2 adapters that make it work (M18x1.5 to 5/8x24, then 5/8x24 to 1/2x28), but would much rather just have 1 adapter instead of stepping down with 2 adapters.
